The Miyagi and Iwate prefectures think that the number of people who are dying alone is increasing because there are many cases of people living in temporary housing who struggle with daily life and have no one to take care of them.
I'm struggling to parse the part in bold in a convincing way. I'll try to break it down:
There are many cases of people living in temporary housing.
What kind of people?
People who struggle with daily living
The part I'm stuck on is how to join all of this with
Old people who have no one to care for them
I don't understand how this fits with the rest of the sentence. At first I assumed that お年寄り was the subject of 困っている but then I have
So the subject appears twice in this clause, both as the actual subject and the relativised (is that a word?) noun. This doesn't seem right.
What am I getting wrong here?
